Why am I so tired?

Tiredness and fatigue are common side effects of quitting. Luckily, they are temporary and will go away as your body adjusts to life without nicotine. Some people also say they have trouble sleeping when they quit smoking. Getting some exercise each day can help you sleep better at night. It’s also a great way to keep busy and boost your mood while you’re quitting. Cutting back on caffeine and alcohol can also help you sleep better.
